[PATCH] [POWERPC] 4xx: Fix 460GT support to (re-)enable the FPU

[Stefan Roese]

Since AMCC now reports that the 460GT *has* an FPU, we should enable it
(again). This patch basically reverts my patch
acb0142bf01c0ebe18f09e37814451ee6a873e27 ([POWERPC] 4xx: Fix 460GT support
to not enable FPU), which disabled the FPU upon AMCC request.

Sorry about the confusion here.
